Front 13

The future growth of large-scale hydropower plants in the developed world probably will be limited because

Back 13

the release of impounded water alters streamflow patterns


most economical sites are already used


reservoirs eventually fill with sediment


the addition of reservoirs mean that more water is lost to evaporation
